SPECIFICATION forming part of Letters Patent N 0. 709,190, dated September 16, 1902.

Application filed January 17. 1902. Serial No. 90,173. (No model.)

To all whmn it may concern.-

Be it known that I, JACOB P. WRIGHT, of Akron, in the county of Summit, and in the State of Ohio, have invented certain new and .5 useful Improvements in Dipping-Rolls for Match-Machines; and I do hereby declare that the followingisafull, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure l is a longitudinal section of a composition-applying mechanism embodying my invention; Fig. 2, an end elevation thereof; Fig. 3. a cross-section on the line as of Fig. 1; Fig. 4, a perspective view .of the roll, and I 5 Fig. 5 a perspective view of the roll-shaft.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to provide a composition-applying mechanism for matchmachines having a dipping-roll constructed to serve as a composition-mixing device; and to this end my invention consists in the roll constructed substantially as hereinafterspecified.

In the carrying of my invention into practice any desired form of composition-holding receptacle A may be employed. Said receptacle or vat A has in cross-section a lower portion that is semicircular and an upper portion with straight outwardly-flaring or diverging sides and has end walls with bearings for a shaft B, that extends through the vat concentric with the semicircular portion thereof: Equidistant from each other on the shaft are radially-projecting arms or ribs C and C, preferably, but not necessarily, three, on which is mounted the roll D in the form I of a hollow cylinder that extends from end to end of the vat A. Notches d and d, of cono-siderable extent circumferentially, are provided in each end of the roll, through which there may be communication between the inside and outside thereof. The diameter of the roll is such that but a very small space is left between it and the curved lower portion of the vat A. The arms or ribs G and C extend obliquely to the roll-axis, each having a spiral form, and preferably said arms or ribs are shorter than the roll, as shown, to facilitate cleaning the interior thereof. Power for revolving the roll being applied through the shaft B and the proper quantity of composition being in the vat, it will be seen that by the action of the inclined or spiral ribs the composition will be forced longitudinally through the roll, it passing from the interior thereof to the exterior through the notches or passages d and d at one end of the roll and returning to the interior of the roll through the notches or passages d and d at the other end thereof. Besides the movement of the composition lengthwise of the roll produced by the spiral ribs it is evident that it is also moved crosswise thereof and lifted by said ribs, so that thorough mixing is effected by its circulation, and precipitation of the matters of greater specific gravity is prevented. The lugs that are formed on the ends of the roll by the notches d and d therein assist the mixing and prevent pre- 7o cipitation by acting on the composition that passes through the notches,

As a roll of large diameter is secured as a result of my construction, important advantages are gained in the performance of its function in the dipping of the splints. Thus where the composition is light more of it is carried up on the exterior of the roll than is possible with a roll of less diameter, and consequent sharper curvature of its periphery, and for the same reason composition is presented to the splints for a longer period of time, and therefore better results secured in the application of composition to the splints.

It is to be understood that changes in the details ofconstruction I have shown can be made which will involve no departure from the scope of my invention.

Having thus described my invention, what I claim is-- o 1. The combination of a composition vat or receptacle, a hollow dipping-roll, and means within the roll for agitating the composition, substantially as and for the purpose described.

2. The combination of a composition vat or receptacle, a hollow dipping-roll, and means for causing movement of the composition through the roll, substantially as and for the purpose described.

3. The combination of a composition vat or receptacle, a hollow dipping-roll, having passages between its interior and exterior, and

means for causing circulation of the composition into, through and out of the roll, substantially as and for the purpose described.

4. The combination of a composition vat or receptacle, a hollow dipping-roll, having passages between its interior and exterior, and means within the roll for causing circulation of the composition, substantially as and for the, purpose described.

5. The combination of a composition vat or receptacle, a hollow roll, and spiral arms therein, substantially as and for the purpose described.

6. The combination of a composition vat or receptacle, a hollow roll, a shaft, and spiral arms between the shaft and roll, substantially as and for the purpose described.

7. The combinationof a composition vat or receptacle, a hollow roll having passages at its ends, a shaft, and spiral arms between the shaft and roll, snbstantiallyas and for the purpose described.

8. The combination of a composition Vat or receptacle, and a hollow roll whose ends have projecting lugs between which are spaces for the passage of composition, substantially as
